Mars on October 18, 2020 (RGB from Mono)

Acquisition type: Lucky imaging

This is my first RGB image of Mars generated using a mono planetary camera and filters. I picked up an ASI290MM earlier this year with the intent of modifying my imaging setup and learning the workflow for generating RGB images from mono camera captures for this Mars apparition. Well, I finally got around to it and this is the first result for Mars.

Imaged Mars on the morning of October 18, 2020 with average seeing and transparency. Mars was showing a disc ~22 arcsecs in diameter at magnitude of -2.5. The prominent dark albedo feature to the south of the meridian is Mare Cimmerium.

Imaged with a C8 Evo, ZWO filter wheel, ZWO RGB filters, Siebert 2x barlow, ZWO ADC, and ZWO ASI290MM. Imaging train was configured to give ~F/18 (0.165 arcsec/pixel). Image capture using Firecapture with gain/exposures set at : 325/25 ms (red), 300/3.7 ms (green), 300/5.5 ms (blue). Stacking in AutoStakkert3 (best 10% of ~50000 frames captured over ~180 sec per channel). Wavelet sharpening in Registax6. De-rotated 3 sets of images for each filter then and RGB combined resulting R,G, and B de-rotated images in Winjupos. Color balancing of the RGB image in Registax.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
